Abstract:

A full authority digital electronic control system research program with WP-13 as a technology demonstrator was established to provide advanced technology for our coming airbreathing engine control systems. The scope of the research program includes the control theory and methodology, the real-time control system simulation, the automated fault detection, isolation, and reconfiguration algorithm, the built-in digital electronic engine controller with functional and hardware redundancy, the sensing and actuating systems, and the full governing hydromachanical backup control. The paper presents an outline of the program, the motivation of the research, general system description, the goals and technology needs and progress, and the prospects.
